Post-caldera volcanism reveals shallow priming of an intra-ocean arc andesitic caldera: Hunga volcano, Tonga, SW Pacific
Intra-oceanic arcs are typically associated with intermediate (andesitic) cone volcanoes.
However, caldera volcanoes may also form in these settings from very large eruptions …

The genesis of silicic arc magmas in shallow crustal cold zones
A number of currently popular models for the genesis of evolved arc-magmas (from basaltic
andesite to dacite) invoke repeated intrusion, partial-melting and differentiation at the base …
